| Re: How long does it take for battery to drain? I had my rotors and pads done on my car, and the mechanic left the key in the car on but not cranked.
It took them an hour or so to do the the rotors which left my battery dead. They had to jump start it to get it going and its fine afetr tha(driving around charging it)
Overall Cadillacs battery are pretty weak or the car just uses to much battery juice...
Or maybe my two 12" subs took the power? idk |
